Abstract

PURPOSE: To control the contour compensation amount used by a scanning-speed modulator circuit corresponding to bridghtness, by adjusting the clamp potential of a clamp regulator and by enabling a gain control circuit to control the amount of a video signal inputted to the scanning-speed modulator circuit corresponding to the variations of the DC level of the video signal.
